Definitions
- the present invention pertains to the field of illuminated signs, and more particularly to an edge lighted sign.
- the inner chamber also houses a variable duty cycle oscillator, provided with an exteriorly disposed ratio control device or knob to control the blinking cycle of the light source within a range extending between completely “on” and “off” positions.
- a back side of the panel is provided with an opaque coating or covering, or alternatively may be frosted, while a front side of the panel is adapted to receive a message, advertising, etc., applied by permanent materials such as paint, or removable materials such as crayons, for example.
- a frame is preferably secured about the exposed side and top edges of the panel to prevent a light loss therethrough, and a removable bottom panel is provided on the base structure to provide access to the inner chamber light source, which is preferably in the form of a fluorescent light tube.
- one of the principal objects of the present invention is to provide an edge lighted sign including a clear transparent panel having an opaque back side and a transparent or translucent front side which is adapted to receive a message, advertising etc. applied thereto by means of either permanent or removable materials such as paint or crayons, for example, or for displaying photographic transparencies.
- Another object of the invention is to provide a base structure for the panel, providing an enclosed inner chamber for a suitable light source, such as a fluorescent light tube, and a longitudinally slotted top side to slidably receive a bottom edge portion of the transparent or translucent panel into a relatively closely adjacent relationship to the light source.
- a suitable light source such as a fluorescent light tube
- a further object of the invention is to provide a variable duty cycle oscillator, within the chamber, having an exteriorly extending ratio control device or knob.
- Yet another object of the invention is to provide a frame about the outwardly exposed side and top edges of the panel, and a removable bottom panel for the housing, to provide access to the light source and cycle oscillator.
- FIG. 1 is a front elevational view of the edge lighted display sign of the present invention
- FIG. 2 is an elevational view of the left end of the sign as seen in FIG. 1;
- FIG. 3 is a cross sectional view taken along line 3--3 of FIG. 1. The invention will be better understood upon reference to the following detailed description and to the appended claims.
- the edge lighted display sign of the present invention designated generally at 10 includes a transparent panel 12 and a base assembly 14.
- the transparent panel 12 is preferably formed of clear glass, although it may be translucent, including a back side, FIG. 3, provided with an opaque coating or covering 16 and a clear or translucent front side 18 for the reception of any type of message, advertising, etc. in contrasting colors to the opaque back side.
- the term "clear” will be understood to mean either transparent or translucent.
- the back side may be frosted to provide for the display of photographic transparencies.
- the opaque coating or covering 16 may be black, white or other color to contrast with the display on the front side.
- a message, advertising matter, etc. may be removably applied to the clear front side 18 by suitable means, such as crayonds, or permanently applied thereto, as by paint.
- the base assembly 14 includes, first and second side walls 20, 22, first and second end walls 24, 26, and upwardly converging top wall portions 28, 30 to a longitudinally extending central slot 32, which is sized to slidably receive a lower end portion 34 of the panel 12.
- Channel frame portions 36, 38 and 40 cover the opposed side and top edges of the panel 12.
- the respective webs of the frame portions 36, 38 define abutments 40, 42 to limit the penetration of the lower end portion 34 of panel 12 into the chamber 44 of the base 14.
- the bottom end portions 46, 48 of the side frame portions 36, 38 partially overlie the end walls 24, 26, as at 50, and prevent longitudinal displacement of the panel 12, relative to base 14. Screw means (not illustrated) may be utilized to provide a fixed attachment of the panel frame to the base 14.
- a fluorescent light tube 60 is conventionally mounted in opposed end socket members 62, 64, which are fixed at 66, 68 to a removable bottom panel 70 of the base assembly 14. Bottom panel 70 is removably secured in place by a plurality of screws 72.
- a conventional variable duty cycle oscillator 74 is secured within the chamber 44 in any conventional manner, and includes a ratio control device 76 projecting exteriorly of the base 14. Suitable electrical wiring 78, from an electrical source, connects between the oscillator and fluorescent tube 60. Oscillator 74 may be controlled by device or knob 76 from an "off" position for light tube 60 to a constant "on” position, through a complete range of blinking speeds.
